[libc-commits] [libc] Add generic sqrt root headers to libc sqrt specializations (PR #135237)

[Drew Lewis via libc-commits]

https://github.com/calewis created https://github.com/llvm/llvm-project/pull/135237

This header is needed to provide the declaration for the sqrt template.  You can build without these in the CMake build, but not having this include in the architecture specific headers makes them not self contained.
